Ballast water deployment system and working method for a full-turn crane ship

Abstract

The invention discloses an efficient ballast water allocation system of a full-rotation floating crane and a working method thereof. The system comprises a crane monitoring and measurement system, a ship draft monitoring system, a ballast water tank water level measurement system, an alarm system, a central control system (including a ballast water allocation optimization module and an efficient solving strategy) and a ballast pipe allocation system. According to the system provided by the invention, an efficient ballast water allocation scheme aided design based on a computer can be achieved, an allocation scheme is optimized, and optimal allocation time is acquired, so that load adjustment speed and work efficiency are improved, a construction period is saved, use time of large ship equipment is reduced, and thus cost is reduced, and energy saving and emission reduction are achieved. According to the system and the control method thereof provided by the invention, a computer control technology is used, so that automatic ship ballast water allocation and water in / drain work can be achieved to a certain extent. Compared with allocation performed by human experience, computer control is better in control accuracy. Manual control needs to perform allocation work manually, and the computer control technology is simple in operation and high in degree of automation.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a technology and system for deploying ballast water in the process of hoisting cargo by a full-turn crane ship. Background technique [0002] The hoisting and slewing operation of the full-turn crane ship will cause the ship to tilt longitudinally and laterally, which will affect the safety of the ship itself. With the increase of the size of the crane ship, this problem is particularly prominent. The overturning moment generated by lifting heavy objects will cause the heel angle to reach 7- 8°, or even larger. The ballast system can adjust and counteract the huge overturning moment generated by lifting heavy objects by injecting, discharging or deploying ballast water to the ballast water tank of the whole ship, so as to achieve the adjustment of ship draft, hull longitudinal and transverse balance and ship metacentric height. The purpose is to ensure the safety of offshore opera...

Problems solved by technology

The existing ship ballast system configuration usually has the disadvantages of slow load adjustment speed, poor control accuracy and low degree of automation. It is difficult to meet the requirements of frequent changes in sea conditions and fast completion of operations during periods of relatively calm sea conditions. There is an urgent need for efficient automatic deployment of ballast systems and technology
